Answer #1

The statement is False.

Having a linear regression equation allows us to predict a variable score for the range of X values on which the linear regression is estimated. The linear regression equation is based on fitting the straight line with the given values of X. For any value, which is outside the range of X, the relation between X and Y may not have the same linear relation and hence the  linear regression equation cannot be used predict a variable score.
